Product details
Overview
MAX6107EUR+T from Maxim Integrated is a low-dropout, micropower, three-terminal series-mode voltage reference delivering a precise 4.5V output with ±0.4% initial accuracy and 75ppm/°C max temperature coefficient over –40°C to +85°C. It draws only 90µA quiescent current, supports 5mA source / 2mA sink load capability, and operates with input voltages as low as (VOUT + 200mV) - enabling use in space-constrained, battery-powered precision analog systems such as portable DMMs and GPS receivers.
For engineers reviewing the MAX6107EUR+T datasheet, MAX6107EUR+T pinout, MAX6107EUR+T application, or MAX6107EUR+T equivalent, this page delivers verified specifications, SOT23-3 terminal mapping, real-world load regulation behavior (0.9mV/mA sourcing), dropout performance at 1mA (50mV), and validated alternatives for precision voltage reference selection in low-power embedded designs.
Technical Context
The MAX6107EUR+T employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve high stability without external compensation. Its series-mode architecture eliminates dependency on external bias resistors and enables supply current virtually independent of input voltage (4–8 µA/V variation).
Internally compensated for capacitive loads, it remains stable across full load range (0–5mA sourcing, –2mA sinking) without requiring an output capacitor - a key differentiator from shunt-mode references. Dropout voltage is specified at 50mV (max) under 1mA load, supporting operation near battery end-of-life in 4.5V-referenced ADC or DAC systems.

FAQ
What is the minimum input voltage required for MAX6107EUR+T to regulate at 4.5V?
The MAX6107EUR+T requires an input voltage of at least VOUT + 200mV = 4.7V to maintain regulation. This low dropout headroom enables compatibility with tightly regulated DC-DC outputs or boosted battery rails, ensuring stable 4.5V reference operation even as input sources sag near end-of-life.
Does MAX6107EUR+T require an output capacitor for stability?
No - the MAX6107EUR+T is internally compensated and stable with any capacitive load, including 0 pF. Unlike many references, it does not require an external output capacitor, eliminating board space and BOM cost while simplifying design for portable DMMs and GPS receivers where layout area is constrained.
What is the load current capability of MAX6107EUR+T?
The MAX6107EUR+T can source up to 5mA and sink up to 2mA while maintaining output accuracy within specification. This dual-direction capability supports driving ADC reference inputs, DAC buffers, and comparator thresholds - unlike shunt references limited to sinking only.
How does MAX6107EUR+T compare to shunt-mode voltage references in power efficiency?
The MAX6107EUR+T draws only 90µA quiescent current independent of load, whereas shunt references waste current through a series resistor even at zero load. This makes MAX6107EUR+T ideal for battery-powered systems - delivering up to 10× longer runtime than shunt equivalents under light-load conditions.
Is MAX6107EUR+T suitable for automotive temperature ranges?
The MAX6107EUR+T is specified for –40°C to +85°C, meeting extended industrial requirements but not the full AEC-Q100 Grade 2 (–40°C to +105°C) automotive range. For automotive cabin or infotainment applications within its rated range, it provides reliable 4.5V referencing with 75ppm/°C stability and ±0.4% accuracy.
